tha Gaolo^'ieal Survey for which he was responsible. This — Th(^ Uric/in 

 of the British Flora — though a thin voliiine of less than 200 pages, 

 was a very important work, dealing in a masterly way with the means 

 of dispersal of plants generally, and the changes in the geography and 

 cliiniite of this part of Europe,' from the newer Pliocene period 

 onward. It also enumerated the results of the author's many years 

 of patient research, in the shape of lists of the species of plints 

 found in the various deposits with the conclusions drawn therefrom. 

 The latter half of the book consists of a systenritic account of the 

 history of our present Hora as indicated by the geological evidence. 



In 1901 and 1903 he published notes on the plant remains of 

 Roman Silchester *, and in the latter year " Notes on the seeds of 

 plants found in the alluvium of the River Lea at Walthamstow " t. 

 In 1902 he contributed the article " Pala^o-botany, Tertiary" to the 

 Tiiiws edition of the Encijclop(edia Britannica ; this article slightly 

 revised appears in the current edition. 



In 1905 he visited Tegelen in Holland, where some interesting 

 fossil plant-remains had been found in a bed of brick-earth, judged 

 to be about contemporaneous with the Cromer Forest Bed. In 

 1907 he and Mrs. Reid published the result of their woi'k on 

 the material obtained there in a fine memoir, "The Fossil Flora of 

 Tegelen sur Meuse";];, followed in 1908 by a paper on D/dichitfm 

 vrspi forme, a new species §, and in 1910 by '' A further investigation 

 of the pliocene Flora of Tegelen " |{. These three papers are illustrated 

 with numerous admirable micro-photographs of the seeds etc. by the 

 authors. In the course of this investigation startling results were 

 obtained. Eastern Asiatic types being found in comi)any with the 

 ordinary European ])lants of to-day. 



In 1907, while Reid was stationed in North Cornwall, he had a 

 visit from Pi'ofessor Nathoi-st the eminent Swedish ])ala'o-botanist, 

 whose work he much admired and for whom he had a great personal 

 regard. This visit afforded the opportunity for discussing and ct)m- 

 paring notes on the problems connected with recent geological changes 

 in which both were so much interested. 



In 190-S the Reids produced an important paper on the Pre-(}lacial 

 Flora of Britain ^, in which 151 species were enumerated, the 

 illustrations being still better than those of the Tegelen papers. In 

 1910 thev contributed an illustrated paper on 'The Lignite of Bovey- 

 Tracey**, dealing with the ])lants of a much earlier [)eriod, and in this 

 .several new species were described. 



In 190S Reid went out to Cyprus on behalf of the Colonial Office 

 to re]x)rt on the water .>up]jh', and made a small collection of plants, 

 which was worked out at Kew. In 1911, at the British Association 

 meeting at Portsmouth, he read a paper and opened a discussion on
